Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may determine, via a first subscription of the UE, a trigger event for a conditional handover of the UE from a source network entity to a target network entity. The UE may determine, based at least in part on the trigger event, that a target band associated with the target network entity is not compatible with a serving band associated with a second subscription of the UE. The UE may store the trigger event for the conditional handover in a buffer of the UE. The UE may perform an action related to the conditional handover based at least in part on a condition being satisfied. Numerous other aspects are described.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may transmit, via a subscription of the UE to a network node, a UE assistance information (UAI) that indicates a reduction to one uplink multiple-input multiple-output (MIMO) layer for the subscription. The UE may transmit, via the subscription to the network node, an uplink transmission using one uplink MIMO layer on one transmit (Tx) chain of the UE based at least in part on the UAI and a timer associated with the UAI. Numerous other aspects are described.

Abstract: A multi-SIM user equipment (UE) can perform link failure operations associated with a first universal subscriber identity module (USIM) in an active state during a time gap when the UE can perform a network operation on a second USIM in a non-active state. The UE can monitor a failure event associated with the first USIM using a first procedure. The failure event includes a radio link failure, a beam failure, and/or a listen-before-talk (LBT) failure. The UE can transmit a request to a network entity for a time gap to perform a network operation associated with the second USIM, while the first USIM remains in a radio resource control (RRC) connected state during the time gap. The UE can monitor, using a second procedure during the time gap, the failure event associated with the first USIM.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may generate, based at least in part on a handover condition being satisfied, a message that indicates that the UE is preparing to leave a source cell for a target cell. The UE may transmit the message before a conditional handover (CHO) is initiated or during a wait timer that is started after the CHO is initiated. Numerous other aspects are described.

Abstract: Certain aspects of the present disclosure provide techniques for releasing an RRC connection by a user equipment (UE). A method that may be performed by the UE includes establishing an RRC connection, determining a time duration for a release timer, resetting the release timer, monitoring the RRC connection, and releasing the RRC connection.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment may receive bandwidth part configuration information configuring a dormancy profile for a first bandwidth part of a plurality of bandwidth parts; communicate, on a second bandwidth part, a plurality of types of signaling; and communicate, on the first bandwidth part, a subset of the plurality of types of signaling, such that at least one type of signaling, of the plurality of types of signaling, is suppressed in accordance with the dormancy profile. Numerous other aspects are provided.

Abstract: In a dual network link scenario, a wireless network may provide a user equipment (UE) with a measurement configuration indicating multiple inter-frequency measurement objects during an off duration of a discontinuous reception (DRX) cycle configured on a first network link. The UE may assign the inter-frequency measurement objects to a second network link if the second network link has an always-on configuration. Alternatively, if the second network link has a DRX configuration, the UE may perform some inter-frequency measurement activities on the first network link and assign some inter-frequency measurement objects to unoccupied gap occasions in the off duration for the DRX cycle configured on the second network link. In this way, the UE may save power by spending more time in a low power state, and mobility performance for the UE may be improved by increasing the efficiency and reliability of inter-frequency measurement activities.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may determine whether a slot timing difference, between a first cell and a second cell for a dual connectivity mode, satisfies a threshold value, where the first cell is a serving cell associated with a first radio access technology (RAT) and the second cell is a serving cell or a candidate cell associated with a second RAT. The UE may perform an operation to prevent the dual connectivity mode with the second cell, establish the dual connectivity mode with the second cell, maintain the dual connectivity mode with the second cell, or terminate the dual connectivity mode with the second cell based at least in part on whether the slot timing difference satisfies the threshold value. Numerous other aspects are provided.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may initiate a broadcast or multicast (broadcast/multicast) application associated with a first radio access technology (RAT) while the UE is in a standalone mode for a second RAT; switch from the second RAT to the first RAT based at least in part on initiating the broadcast/multicast application; and switch from the first RAT to the second RAT based at least in part on failing to detect a communication associated with the broadcast/multicast application using the first RAT. Numerous other aspects are provided.

Abstract: Disclosed are techniques for enabling a user equipment (UE) operating in carrier aggregation mode to use different connected mode discontinuous reception (CDRX) configurations for different sets of component carriers associated with different sets of numerologies. For example, in Frequency 1 (FR1) plus Frequency 2 (FR2) carrier aggregation (i.e., one or more FR1 component carriers and one or more FR2 component carriers), a different CDRX can be configured for FR1 than for FR2. In inter-band carrier aggregation (i.e., one or more component carriers in one frequency band and one or more component carriers in another frequency band), CDRX can be configured per band. For mixed numerologies carrier aggregation (i.e., one or more component carriers with a first numerology and one or more component carriers with a different numerology), CDRX can be configured per cell group, where each cell group contains a single numerology or mixed numerologies.
